饮水温度对崂山奶山羊产奶性能的影响
Effect of Drinking Water Temperature on Milk Performance of Laoshan Dairy Goats
摘要
Abstract
The aim of the experiment was to study the effect of drinking water temperature on the milk performance of Laoshan dairy goats in cold winter.Therefore,some late lactation Laoshan dairy goats which in the similar level of milk yield,weight,date of lambing,healthy lactation peak were selected in our experiments,and one–factor completely random design had been adopted in these trials.With 5℃water as the contrast,16、22、28℃water were given for Laoshan dairy goats respectively.Some important results were as followingalong with the increasing of water temperature,the milk output and the drinking amount increased.Compared with 5℃group,the milk output of 16℃group,22℃group,28℃group significantly increased by 16.2%、18.4%、23.1% respectively(P<0.05).On the whole,the butterfat content and milk protein rate decreased as water temperature rised,but the butterfat content and milk protein rate in 22℃group were higher than that in 16℃group and 28℃group.We suggested giving Laoshan dairy goats warm water at the temperature of 22℃in cold winter,so that we could get more milk and assure quality at the same time.关键词
